Trump will never hold national office in this country. Ever. I voted for him twice and, I assure you, I would not vote for him a third time, and I know a lot of former Trump supporters who feel the same.
Unfortunately, there are more Trump supporters who are not as reasonable as you. According to several polls taken since the Capitol Riot, about a third of folks in this country still approve of the Pres. (see 538). Rasmussen says half.
I'm reminded that Toronto Mayor Rob Ford's dumber younger brother Doug, is now the Premier of Ontario, and Doug ran on what a great job that he and his brother did when the ran Toronto. The Fords claimed they "saved" Toronto taxpayers $80 million and had the lowest tax increases of any city in North America. None of what they claimed was true at all, but Doug Ford is still repeating these lies, and Ontario voters believed him.
Toronto voters had Rob Ford stripped of all his mayoral powers during his term, so that he was mayor in name only. When Rob Ford dropped out of the election campaign due to his cancer diagnosis, Doug took his place and finished dead last. But Ontario voters believed the fictions, and quickly learned it was all a lie.
If Trump is allowed to go free, and continue to spout his poisonous lies for another four years, unchallenged, you could be right back in same mess you're in now, if Trump or someone worse, is elected in 2024.
